Calacatta Belgia

Calacatta Belgia
quarry of origin

Belgia

Carrara, Italy
Petrografic name (according EN 12407): Marble
Macroscopic description: A compact lithotype that resembles a breccia. This material is composed of white aphanitic clasts up to pluridecimetric in size with fine, faint, yellow-brown-coloured veins immersed in a fine-grained lightish grey groundmass with brown veins in places. Rare surface porosity is apparent.
Technical data provides a frame of reference only. As stone is a product of nature, up to date testing to determine specific physical qualities should be repeated for each major project. We decline any responsability for the mis-use of this data, since said data is sourced from the quarry.

Microscopic description according to EN 12407 e EN 12460
A generally anisotropic metamorphic lithotype with a vague isoorientation of the more elongated crystals and the veins. The blasts are euhedral-subeuhedral with straight grain boundaries that are sutured in places and seriate (from 150 to 600 µm) and a crystalline mosaic with blasts from 80 to 200 µm, inside which submillimetric spots can be seen composed of blasts clouded by microgranulations of opaque minerals associated with abundant acicular muscovite and euhedral pyrite (< 400 µm). The veins are composed of calcite microcrystals clouded by microgranulations of opaque minerals, acicular muscovite, rare quartz and feldspar crystals and rhombic dolomitic crystals.
